I am looking for a document scanner for windows 10 (for my surface tablet) to convert paper documents via camera to multipage pdf documents. Something like Genius Scan but for Windows.


  • Multipage pdf creation
  • Ad Free
  • No login/account required
  • free or paid (but just pay once!)
  • Convenient to use
  • Should produce reasonable small pdf file sizes

Nice to have:

  • Automatically adding an ocr layer for machine typed documents
  • Automatic document detection
  • Automatic perspective correction
  • Adjustable output resolution

The one which I use and highly recommend is NAPS2.

  • It is open source and ad-free.

  • Has OCR, Multipage pdf creation, etc.

  • No login/account required.

  • It produces reasonably small files.

  • You can even use it to split and/or merge old files (pdfs, images) by dragging files into console, and manipulating each page.

It has not been updated for a couple of years, but it works very well.

  • Does this work with camera as input? For me it seems just to work with Scanners? Maybe there is a way to covert the camera to a virtual scanner device or something like that?

  • Not done that myself. Check the issues queue. A way to do this is take your images with camera, then drag into NAPS2 to do OCR/merge etc.

  • Also, note that you can use something like Scan Tailor scantailor.org to clean up images, fix orientation, deskew etc.
